In his place steps Caio Magalhaes (5-1 MMA, 0-1 UFC), who now meets Kuiper in a middleweight matchup.

UFC officials today announced the change for the event, which takes place Jan. 19 at Ginasio Estadual Geraldo Jose de Almeida, also known as Ginasio do Ibirapuera, in Sao Paulo.

The evening’s main card airs on FX, but Kuiper vs. Magalhaes is expected to take place on the evening’s preliminary card.

Magalhaes fights in the octagon for the first time since a June loss to Buddy Roberts at UFC on FX 3. “Hellboy” looked fatigued in the later rounds of the fight as he struggled to take the fight to the floor and suffered the first professional loss of his career. The bout also marked Magalhaes’ first fight outside of his native Brazil.

The 24-year-old Magalhaes is a Brazilian jiu-jitsu black belt and earned his first career MMA victory via omo plata.

Meanwhile, Dutch prospect Kuiper returns after a hard-fought TKO win over Jared Hamman at August’s UFC 150 event. That result marked Kuiper’s first octagon win after he, too, suffered his first career defeat during his octagon debut.

The 23-year-old Kuiper is a judo black belt but has also shown heavy hands, and 11 of his 12 career wins have come via stoppage.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
